Resumo: | International entities have been making an effort for the divulgation of techniques that facilitate the study and conservation of historical building and works of art. Photogrammetry is crucial in this context since it allows the metric morphologic reconstitution of the examined object. At present, digital amateur cameras have been used in the architectural photogrammetry, but the attainment of geometric precision is only reached following the relatively complex photogrammetric procedures, so such calibration, control point surveying, adjustment of the phototriangulation and compilation by using special hardware and software. However, for some types of works so such cadastre for future restoration of buildings with facades that have a predominant vertical plan, it is possible to carry out the survey with simpler methods. This work shows a system of low cost for images acquisition, that is formed by an unexpensive digital camera, direct measurements with tapes and processing of the images by programs that correct lens distortion and perform rectification. The rectified images can be used to compose an archive of low cost and they can be restituted for attainment of the measures in programs type CAD. The method was applied in the Church of Nossa Senhora do Rosário in Recife, PE. |

Reconstitution of facade digital image by means of calibration of lens distortionRETIFICAÇÃO DE IMAGENS DIGITAIS DE FACHADAS COM PRÉ-CORREÇÃO DAS DISTORÇÕES DAS LENTESInternational entities have been making an effort for the divulgation of techniques that facilitate the study and conservation of historical building and works of art.

A fotogrametria arquitetural é importante neste contexto porque permite a reconstituição métrica e morfológica do objeto examinado e atualmente pode se beneficiar com a crescente oferta de câmaras digitais amadoras. Porém uma precisão geométrica adequada só é obtida com essas câmaras seguindo procedimentos relativamente complexos para nãofotogrametristas, como calibração, medição dos pontos de apoio com estações totais, ajustamento da fototriangulação e restituição com equipamentos e programas especiais. Por outro lado para alguns tipos de trabalhos de cadastro para futuras restaurações de prédios, que têm planos verticais predominantes nas fachadas, é possível realizar o levantamento com métodos mais simples. Este trabalho mostra o desenvolvimento de um sistema de baixo custo para aquisição das imagens, composto por câmara digital com 2048x1536 pixels, medições diretas com trenas e processamento das imagens com programas para correção das distorções das lentes e retificação. As imagens retificadas podem ser usadas para compor um arquivo a custo baixo e que podem ser restituídas para obtenção de medidas em programas tipo CAD. O método foi aplicado na Igreja de Nossa Senhora do Rosário em Recife.Boletim de Ciências GeodésicasBulletin of Geodetic Sciences2006-06-30info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://revistas.ufpr.br/bcg/article/view/5325Boletim de Ciências Geodésicas; Vol 12, No 1 (2006)Bulletin of Geodetic Sciences; Vol 12, No 1 (2006)1982-21701413-4853reponame:Boletim de Ciências Geodésicasinstname:Universidade Federal do Paraná (UFPR)instacron:UFPRporhttps://revistas.ufpr.br/bcg/article/view/5325/3937DA SILVA, DANIEL CARNEIROinfo:eu-repo/semantics/openAccess2006-06-26T18:43:29Zoai:revistas.ufpr.br:article/5325Revistahttps://revistas.ufpr.br/bcgPUBhttps://revistas.ufpr.br/bcg/oaiqdalmolin@ufpr.br|| danielsantos@ufpr.br||qdalmolin@ufpr.br|| danielsantos@ufpr.br1982-21701413-4853opendoar:2006-06-26T18:43:29Boletim de Ciências Geodésicas - Universidade Federal do Paraná (UFPR)false |
